<p>I just picked that arbitrarily for another test to go with my Math II. From the questions I've seen, it just seems like Critical Reading.</p>
<p>SAT Literature focuses mostly on novels and poetry, whereas the Critical Reading section of the SAT I focuses on factual texts as well. Some prep organizations recommend taking the Literature test only if you have over 600 in the CR section.</p>
<p>Just knowing some vocabulary for interpreting literature will help. It does have a very difficult curve though.</p>
